NASA's Mars Exploration Rover (MER) mission was a robotic space mission involving two Mars rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the launch of the two rovers to explore the Martian surface and geology ; both landed on Mars at separate locations in January 2004.
NASA's Curiosity rover, selfie, 2015. A Mars rover is a remote-controlled motor vehicle designed to travel on the surface of Mars. Rovers have several advantages over stationary landers: they examine more territory, they can be directed to interesting features, they can place themselves in sunny positions to weather winter months, and they can advance the knowledge of how to perform very ...
Perseverance [2] is a car-sized Mars rover designed to explore the Jezero crater on Mars as part of NASA's Mars 2020 mission. It was manufactured by the Jet Propulsion Laboratory and launched on July 30, 2020, at 11:50 UTC. [3] Confirmation that the rover successfully landed on Mars was received on February 18, 2021, at 20:55 UTC.
Opportunity, also known as MER-B (Mars Exploration Rover – B) or MER-1, and nicknamed Oppy, is a robotic rover that was active on Mars from 2004 until 2018. [1] Opportunity was operational on Mars for 5111 sols (14 years, 138 days on Earth).
Spirit, also known as MER-A (Mars Exploration Rover – A) or MER-2, is a Mars robotic rover, active from 2004 to 2010. [4] Spirit was operational on Mars for 2208 sols or 3.3 Martian years (2269 days; 6 years, 77 days). It was one of two rovers of NASA's Mars Exploration Rover Mission managed by the Jet Propulsion Laboratory (JPL).
By Eric Sandler On August 20, 1975 -- 39 years ago today -- NASA launched the first of two spacecraft as a part of their new Viking program and the images they captured back in the '70s and '80s ...
With an average speed of about 20 centimeters per second (five times faster than the Curiosity rover's top speed on mars) the RASSOR will work 16 hours a day for many years (a minimum of 5 years as stated in the design requirements). [2] In its design NASA has moved away from its usual fragile and slow robot to design something more robust and ...
The setting is JPL's Mars Yard testing area. Front and center is the flight spare for the first Mars rover, Sojourner, which landed on Mars in 1997 as part of the Mars Pathfinder Project. On the left is a Mars Exploration Rover Project (MER) test rover that is a working sibling to Spirit and Opportunity, which landed on Mars
